Mark Knopfler blew us all away by reminding us that the best sounds come from a skilled set of hands - not a pile of effects pedals!
The twistin' truth is that what really made this song special was that it was released to a Rock audience. Good country music has featured that sound, and similar style, since very nearly forever. If it had been released as a country song, it would have been enjoyed for a while by some, criticised by others because the vocals sounded like a city-boy, and then left to fade away. It's sad to think how much good stuff people miss by ignoring other genres.
